Quanex Building Products Corp is a Construction company. Its directors and officers file their transactions with SEC (Form 4). Over the twelve months to 18 October 2026, 8 filings were filed, from 8 insiders.
The flow runs one way only: 1 sale worth €1.1M, from 1 insider, and no purchase. At €1.1M, the sale published on 18 December 2025 by Teleios Capital Partners GmbH is the largest of the period.
For context, the typical company on the same exchange (median of 5,816 companies) published 19 filings over the same period, against 8 filings here. Looking back to 2016, when coverage begins, insiders filed 9 purchases and 15 sales. The 10-K for the year ended 31 October 2025 shows 1.84 bn USD of revenue and -250.8 m USD of net income and a dividend of 0.32 USD per share.
The median gap between a trade and its publication by SEC (Form 4) is 4 days. US insiders must file a Form 4 within two business days of a trade. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

Quanex Building Products Corporation (NYSE:NX) is a U.S.-listed building-products manufacturer headquartered in Houston, Texas, United States. The company traces its roots back to 1927, when it was founded as Michigan Seamless Tube Company. Over time, Quanex has transformed through a series of acquisitions and strategic portfolio shifts into a global supplier of engineered components for the building industry. Today, it operates more than 67 facilities worldwide and positions itself as a solutions provider focused on innovation, energy efficiency, and sustainable building performance.
Quanex’s core business is centered on components and systems used by original equipment manufacturers (OEMs) in fenestration, cabinetry, and related building applications. Its product set includes insulating glass spacers, vinyl extrusions, seals, and weatherproofing components for windows and doors, as well as access hardware and other engineered solutions. The company also serves cabinet and kitchen-related markets with specialized components. This diversified product mix gives Quanex exposure to several end markets while keeping the business anchored in technical, specification-driven products rather than commoditized materials.
From a competitive standpoint, Quanex is best viewed as a niche industrial supplier with differentiated engineering capabilities. Its value proposition lies in materials science, process engineering, product design, and the ability to support OEM customers with performance-critical components. In the fenestration market, where thermal performance, durability, and assembly quality matter, Quanex’s products can be embedded in larger systems and are often selected for long-term reliability and efficiency benefits. That positioning helps the company compete on technical merit, customer relationships, and breadth of offering.
A major strategic milestone was the acquisition of Tyman, completed on August 1, 2024. Management said the transaction created a more comprehensive solutions provider, enhanced scale, broadened the product portfolio, and expanded global reach. In practical terms, the deal strengthened Quanex’s presence across hardware solutions and improved its ability to serve a wider customer base with a more complete offering. The acquisition has also become central to the company’s current financial narrative, with management highlighting cost synergies and integration progress in recent results.
Recent headlines have emphasized both the benefits and the challenges of this transformation. In fiscal 2025, Quanex reported significantly higher sales versus the prior year, largely reflecting the contribution from Tyman. At the same time, the company noted macroeconomic softness, weaker consumer confidence, and some operational issues at a window and door hardware plant in Monterrey, Mexico. Management remains cautious on near-term demand but continues to focus on integration, synergy realization, debt reduction, and selective share repurchases. For investors, Quanex is a NYSE-listed U.S. industrial company tied to residential construction, building efficiency, and engineered components with international reach.
